Polymer ball bearings

SKF polymer ball bearings are typically used in applications where resistance to moisture or chemicals is essential and steel bearings cannot be used or only with certain restrictions. In those applications, polymer ball bearings are an excellent solution from both a technical and economic perspective as they are characterized by the following properties:

corrosion and chemical resistant

high wear- and fatigue-resistant polymer

self lubricating (no lubricant required)

low coefficient of friction

quiet running

lightweight

high specific strength (strength to weight ratio)

high dimensional stability due to the low tendency to creep

low lifecycle costs

electrical insulator

These properties make polymer ball bearings appropriate for the following industries and applications:

Designs and variants

Both bearing designs have uninterrupted raceways and are non-separable. Standard bearings are only available as open bearings (without seals or shields).

On request, other polymer bearings or units are available (fig. 3). Customized polymer bearings can be manufactured economically even in small quantities. Integrated functions (e.g. gearing, specific shape of the bore, etc.) that can reduce the number of components and assembly costs are also possible. Examples of those bearings, which are not provided here, include:
